Hi, my name is (твоё имя на английском) and i want to tell you about my hobby. My favorite hobby is video games. Gaming helps me to go out from the real world to the world of violence and punishment. Adult games helps me to relax, after hard day in a school. In my opinion, games is a new kind of art today, because only in the video games you can put on the mask of a mindless murder. My favorite game is "The POV", because it's the best game with HD graphics. The second plus of this game is a special joypad, which can be controlled only by male. That's all i can tell you about my hobby.

-6 + z = 0 (-3.8):x = 38 2(x+3) = 12
Z = 6. x = -3.8:38 2x + 6 = 12
x = -0.1 2x = 6
x = 3
z/5 + 3 = -7 8x - 12 = 3x + 8 0.8у+1.2=0.4у-2.8
z/5 = -10 5x = 20 0.4y = -4
z = -50 x = 4 y = -10
6х-скорость вертолета
2*х - расстояние которое проехала машина за 2 часа
2*6х - расстояние которое пролетел вертолет за 2 часа
составляем уравнение
2*х+510=2*6х
х=51 скорость машины
6х=306 скорость вертолета
